Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention, in a refuse transporting device of a refuse processing facility, detects such refuse at a stage prior to the processing step so as to extract the refuse that is not suitable for performing a predetermined process from the transfer path. The present invention relates to a marking device that is not suitable for processing and that is used as a mark for removing it.

[0002]

2. Description of the Related Art When crushing waste that has been carried in a waste treatment facility, if, for example, a gas cylinder (mainly medium or small size) is present in the waste, residual gas in the gas cylinder leaks due to crushing. There is a risk of ignition and explosion from sparks due to impact during crushing. Even if the explosion does not occur, the claws of the crusher may be damaged by crushing the rigid cylinder. Therefore, it is necessary to find and extract such an unsuitable material for crushing treatment on the waste transport path before sending it to the crushing treatment step. However, when undesired crushing treatment is buried in a large amount of waste that is transported or is put in a bag, it is often impossible to visually detect it. Therefore, for example, Japanese Patent Laid-Open No. 8-810
According to the conventional dust carrier described in Japanese Patent No. 38,
The dust conveyed on the conveyor is irradiated with X-rays, and a suspicious crushing-incompatible object is detected based on the X-ray image, and the operator determines that the crushing-incompatible object is inappropriate. If you press the switch, spray the colored liquid onto the trash. In this way, a marking is applied to the position where the unsuitable crushing treatment is present, and the unsuitable crushing treatment is extracted by the extracting device depending on this marking.

[0003]

However, in the above-mentioned conventional apparatus, since the coloring liquid is sprayed by a person pressing the switch, the timing of pressing the switch is too early or too late. Sometimes. In such a case, marking is performed at a position that is deviated to the front and back from the position where the unsuitable crushing treatment is present. As a result, even if the dust at the marking position is extracted, the material that is not suitable for the crushing process is not included in it, so the extraction is unsuccessful,
Occasionally, it passed unsuitable materials for crushing. In some cases, the operator forgets to press the switch. Therefore, it was not possible to eliminate the risk of explosion and damage to the claws of the crusher as described above.

In view of the above-mentioned conventional problems, the present invention provides a marking device for improper processing which can surely mark the existing position of the improper processing object when it is detected. To aim.

[0005]

A marking device for improper processing of the present invention comprises a conveyor (7) for conveying dust, and means for detecting improper treatment (2, 8) for detecting improper treatment in the conveyed dust. ) And marking means (9, 1) for marking dust at a position separated by a predetermined distance in the transport direction from the position where the unsuitable object detection means detects an unsuitable object.
0, 13, 14), distance detecting means (1, 6) for detecting the conveying distance of the conveyor from the time when the processing inappropriate object is detected by the processing inappropriate object detecting means, and for driving the marking means. Commanding means (3, 4, 5) for outputting an operation command including the marking command, and the processing inappropriate object detecting means detects an inappropriate processing object, the convey distance of the conveyor reaches the predetermined distance. The control means (1) drives the marking means according to the marking instruction at a time point and stops the conveyor if the operation instruction is not given by the time point. In the parentheses, reference numerals are given to corresponding parts in the embodiments of the invention described below (the same applies hereinafter). When the marking command is issued early by the control means, the marking device for unsuitable processing configured as described above waits until the unsuitable object reaches the position suitable for marking, and Have marking done when reaching a position. Further, when the unsuitable material reaches the same position without outputting the operation command, the conveyor is stopped to prevent the object suspected of the unsuitable material from being conveyed to the crushing process. Therefore, if an unsuitable material is detected, the marking can be properly performed even if the timing of issuing the marking command is too early, and the passing of the unsuitable material can be prevented without marking. be able to.

Further, the control means may be configured to drive the marking means in accordance with a marking command received after the conveyor is stopped when the operation command is not given by the time point. With such a configuration, the operation command is not output, and when the conveyor is stopped, the marking is performed by the subsequent marking command. Therefore, even if the marking command is delayed or forgotten, the marking can be surely performed.

Further, the command means comprises a marking switch (3, 4) for outputting a marking command and a path switch (5) for outputting a marking stop command, and the control means is When the marking stop command is received, the driving of the marking means may be stopped to drive and hold the conveyor. With such a configuration, by issuing a marking stop command from the pass switch, it is possible to convey an object that has been erroneously detected as an inappropriate processing object to the processing step.

Further, the control means, when the processing inappropriate object is detected by the processing inappropriate object detecting means, and the marking instruction is given before the conveying distance of the conveyor reaches the predetermined distance, A marking permission command (Sm) is output at the time when the predetermined distance is reached, the conveyor is stopped when the operation command is not given by that time, and the marking command is given after the stop. In that case, the main control means (1) which outputs a marking permission command at that time and the marking command are latched and held, and the marking means is driven and latched in accordance with the marking command and the marking permission command. It may be constituted by the marking control means (20) for releasing the marking command in time. In the case of such a configuration, the marking control means is caused to carry out the control relating to the marking, whereby the control load of the main control means can be reduced. For example, even when a plurality of marking commands for marking on the left side and the right side of the conveyor in the conveying direction are issued one after another, the marking control means can reliably process the signal, so that the one issued later can be used. A marking command can also be reliably detected.

FIG. 4 is a perspective view showing the structure of the dust transport path, and FIG.
FIG. 8 is a flow chart of control executed in (FIG. 1), FIG. 8 is a sectional view of the conveyor 7 in a direction orthogonal to the transport direction,
FIG. 9 is a perspective view showing the configuration of one end of the conveyor 7. First, the waste transport path and its peripheral structure will be described.

In FIG. 2, a conveyer for conveying dust (only the gas cylinder 12 in the bag is shown, but actually, a large amount of dust is placed as shown in FIG. 8). 7 is driven by a drive mechanism (not shown) and moves in the direction of arrow A in the figure to pass through the inside of the frame 11 having the openings 11a at both ends. The rotary encoder 6 provided on one of the rollers supporting both ends of the conveyor 7 (see FIG. 9) rotates with the movement of the conveyor 7 and outputs the number of rotations, that is, the number of pulses according to the transport distance of the conveyor 7. A pair of colored liquid ejectors 13 and 14 are provided on the upper portion 11b of the end face on the outlet side of the frame 11, and the colored liquid is ejected in a spray form by exciting electromagnetic valves 9 and 10 (FIG. 1) described later. It is designed to be able to mark garbage.

An X-ray irradiator 8 is provided above the frame 11 and irradiates the conveyor 7 with linear X-rays from above the dust in a width direction orthogonal to the conveying direction of the conveyor 7. On the other hand, in the lower part of the conveyor 7 in the frame 11, the X-ray detector 2a is provided in the width direction orthogonal to the conveying direction of the conveyor 7 via a member (not shown) having a linear slit B formed therein. This allows the dust to pass through, and
The X-rays that have passed through the slit B are detected. X-ray detector 2a
The X-ray inspection apparatus main body 2b connected to the
The linear X-ray image from is scanned by the movement of the conveyor 7 to obtain a two-dimensional image, and based on this, it is determined whether or not the object to be photographed is not suitable for crushing processing. The detection signal of is output. As a determination method, for example, X
The number of pixels in the shaded area of the line image is counted, and if the number of pixels exceeds a predetermined reference value, it is determined that the material is not suitable for crushing processing. The X-ray detector 2a and the X-ray inspection apparatus main body 2b constitute the X-ray inspection apparatus 2.

A monitoring board 15 is connected to the X-ray inspection apparatus 2, and the X-ray image signal and the detection signal are sent to the monitoring board 15. The monitor panel 15 has two monitors 16 and 17 built therein, one monitor 16 always displays a moving image (when the conveyor 7 is moving) by an X-ray image signal, and the other monitor 17 is When there is no detection signal of the unsuitable crushing processing, the same image as the monitor 16 is displayed, but when the detection signal of the unsuitable crushing processing is received, a still image at that time is displayed. The control panel 1 (FIG. 1) of the marking device for improper processing is built in the monitoring board 15. Further, the monitoring board 15 is provided with marking switches 3 and 4 and a pass switch 5 for the function of the marking device for inappropriate processing. The marking switch 3 is provided corresponding to the electromagnetic valve 9 (FIG. 1) and the colored liquid ejector 13, and the marking switch 4 is provided corresponding to the electromagnetic valve 10 (FIG. 1) and the colored liquid ejector 14, respectively. Pass switch 5 is X
Even if the line inspection device 2 issues a detection signal of an unsuitable crushing process, to output a "marking stop command" to intentionally pass an object without marking according to the operator's judgment. It is a switch provided.

Next, the connection between the control device 1 and each part will be described. In FIG. 1, the control device 1 includes a CPU, a memory,
The input / output interface and the like are included, and a detection signal of an unsuitable crushing process from the X-ray inspection apparatus 2, three types of operation commands, that is, a left marking command from the marking switch (left) 3, a marking switch (right) 4 The right marking command and the path command from the path switch 5, and the pulse signal from the rotary encoder 6 are input. Further, the output side of the control device 1 is connected to the conveyor 7, the X-ray irradiation device 8, the solenoid valve (left) 9 and the solenoid valve (right) 10, and output signals for driving these are sent.

Next, the operation of the marking device for improper processing configured as described above will be described with reference to the flowchart of FIG. First, by starting the control device 1, a start command is output to the conveyor 7 and the X-ray irradiation device 8 (step 101). As a result, the dust placed on the conveyor 7 is conveyed. X-rays are radiated from the X-ray irradiation device 8 to the conveyed dust,
The X-rays that have passed through the dust are detected by the X-ray detector 2a. When metal is present in the dust, transmission of X-rays is blocked, and the X-ray inspection apparatus main body 2b captures the projected shape of the object as it is transported. Based on this, the X-ray inspection apparatus main body 2b counts the number of pixels of the object, and outputs a detection signal when the number exceeds a predetermined value (Y in step 102). When the number of pixels does not reach the predetermined value (N in step 102), step 102 is repeated.

When the dust contains a gas cylinder 12 as shown in FIG. 2, for example, the number of pixels of the projected shape captured by the X-ray inspection apparatus 2 exceeds a predetermined value. The device 2 outputs a detection signal of an unsuitable crushing process. Then, the control device 1 receiving this starts the measurement of the transport distance of the conveyor 7 from that moment (step 103). That is, counting of output pulses of the rotary encoder 6 is started. On the other hand, when a detection signal of an unsuitable crushing process is sent to the monitoring board 15, a buzzer (not shown) of the monitoring board 15 sounds to notify the operator that the unsuitable crushing processing is detected. Further, as described above, the monitor 17 of the monitoring board 15 becomes a still image, and continues to display the X-ray image of the material unsuitable for the crushing process.

The operator operates the X displayed on the monitor 17.
From the line image, it is determined what the object detected as an inappropriate crushing treatment is, and when it is determined that the crushing is inappropriate (gas cylinder, etc.), the following operation is performed. That is,
Looking at the monitor 17, the object is conveyed 7
If the object is on the right side of the center line of the conveyor 7 with respect to the conveyance direction, the marking switch (right) 4 is turned on if the object is on the left side of the center line of the conveyor. . Further, when the object is substantially in the center of the conveyor 7 in the transport direction, both the marking switch (left) 3 and the marking switch (right) 4 are turned on. On the other hand, if it is determined that the material is not suitable for the crushing process (for example, a thin metal plate), the pass switch 5 is turned on. In some cases, it may be difficult to make a decision, and time may elapse without operating any switch.

That is, the operating situations that should occur are as follows. (1) If none of the switches have been operated, but the conveyance of the predetermined distance has not been performed yet, (2) if the pass switch 5 is turned on, (3) the marking switch 3
Is turned on, (4) the marking switch 4 is turned on, (5) both the marking switches 3 and 4 are turned on, and (6) which switch (3, 4, 5) This is a case where the paper is conveyed for a predetermined distance without being operated. Here, the predetermined distance refers to a distance from the position of the inappropriate crushing treatment at the time when the detection signal is emitted from the X-ray inspection apparatus 2 to a certain position in the vicinity immediately below the colored liquid ejector 13 or 14. . In step 104, the control device 1 waits for the operation of the operator as described above and proceeds the processing. It should be noted that in the determination of the ON state of the marking switch in step 104, in the case of (5), the ON operation of one marking switch is detected because the ON operation of the two switches may be performed back and forth (not simultaneously). In this case, instead of immediately proceeding to step 105, it takes a certain amount of time for the determination of the step to confirm whether or not another marking switch is on.
Hereinafter, description will be made corresponding to the above case classification.

First, in the case of (1), since none of the marking switches 3 and 4 and the pass switch 5 are operated, N of step 104 → N of step 110 → N of step 111 → step 104 is repeated, Wait for a change of state. In the case of (2), step 1 in FIG.
The routine proceeds from N in 04 to step 110, and then returns to step 102, and the unsuitable crushing processing is again detected by the X-ray inspection apparatus 2. That is, in this case, according to the operator's judgment, the marking is not performed, and the object is directly sent to the next processing step.

On the other hand, in the cases of (3), (4) and (5), Y is obtained in step 104 and whether the object has been conveyed for a predetermined distance, that is, the rotary encoder 6
It is judged whether or not a predetermined number of pulses have been counted (step 105). If the sheet is not conveyed for a predetermined distance, the process waits (N in step 105), and if the sheet is conveyed for a predetermined distance, marking is started (step 106). The marking is performed by exciting at least one of the solenoid valves 9 and 10 according to the cases (3), (4) and (5). Specifically, in the case of (3), only the solenoid valve (left) 9 is excited, and the colored liquid ejector 1
The colored liquid is ejected from 3. As a result, as shown in FIG. 3, the coloring liquid is sprayed directly on the crushing-unsuitable material 12 (gas cylinder) that has reached the vicinity immediately below the coloring liquid ejector 13 or on the dust covering it. Similarly (4)
In this case, only the solenoid valve (right) 10 is excited and the colored liquid is ejected from the colored liquid ejector 14 to mark the dust. In the case of (5), both the solenoid valve (left) 9 and the solenoid valve (right) 10 are excited, and the colored liquid ejector 13 is excited.
By ejecting the colored liquid from Nos. 14 and 14, a spraying mode different from the spraying on only one side is performed, which indicates that the crushing treatment unsuitable substance is present in the center.

The above-mentioned jetting of the coloring liquid is performed for a predetermined time (for example, 5
Second) continuously (step 107), and then the marking is stopped (step 108). Next, it is determined whether or not the conveyor 7 is stopped (step 109). If the previous operations are (3), (4), and (5), the conveyor 7 is in operation, so the process returns to step 102 and X is again performed.
The unsuitable crushing process is detected by the line inspection device 2.

In the case of (6), N in step 104 to N in step 110, and further Y in step 111.
After that, the conveyor 7 is stopped (step 112).
Therefore, the object stops in the vicinity immediately below the colored liquid ejector 13 or 14. Then, from this state, it waits until the marking switches 3 and 4 or the pass switch 5 are turned on (N in step 113 to N in step 114). The operation here may be as follows. That is, (7) the marking switch 3 is turned on, (8) the marking switch 4 is turned on, (9) both the marking switches 3 and 4 are turned on, and (10) the pass switch. This is the case where 5 is turned on.

In the cases of (7), (8) and (9), the process proceeds from Y in step 113 to step 106 to start marking. It should be noted that the judgment of the ON state of the marking switch in step 113 is such that in the case of (9), the two switches may be operated ON (rather than simultaneously), so that the ON state of one marking switch is detected. In that case, the process does not shift to step 106 at that moment, but the determination of the same step is repeated within a certain period of time to confirm whether or not another marking switch is turned on. The operation of steps 106 to 108 is as described above, and marking is performed by exciting at least one of the solenoid valves 9 and 10 in accordance with the cases (7), (8) and (9). In this way, if the marking command is delayed (or left out), the conveyor 7
To stop the object below the colored liquid ejector 13 or 14. Then, a marking command is issued during the stop to reliably perform marking. In step 109,
Since the conveyor 7 is stopped, the conveyor 7 is restarted (Y in step 109 to step 115), and then the process returns to step 102, and the X-ray inspection apparatus 2 again detects an unsuitable crushing process.

On the other hand, in the case of (10), step 113
After N through Y of step 114, the conveyor 7 is restarted (step 115). After that, the process returns to step 102, and the X-ray inspection apparatus 2 again detects an unsuitable crushing process. That is, in this case, the operator determines that marking is not necessary in the end, and the dust of the object is not marked and is sent to the next step.

<Embodiment 2> FIGS. 5, 6 and 7 are drawings relating to an apparatus for marking unsuitable objects according to a second embodiment of the present invention. FIG. 5 is a block circuit diagram and FIG. 6 is a marking control of FIG. FIG. 7 is a block circuit diagram mainly showing the internal configuration of the device 20, and FIG. 7 is a flowchart of control executed in the control device 1 (FIG. 5). The difference between the present embodiment and the first embodiment is that the marking control device 20 is provided separately from the control device 1, and the marking command is taken in and the solenoid valve 9 is provided.
The marking control device 20 performs this regarding the driving of 10 and 10, and the control device 1 is configured to perform indirect control by giving a marking permission command to the marking control device 20.

In FIG. 5, the X-ray inspection device 2, the path switch 5, the rotary encoder 6, the conveyor 7 and the X-ray irradiation device 8 are the same as those in the first embodiment, and therefore their explanations are omitted. A marking control device 20 is connected to the output side of the control device 1, and the marking control device 2
A marking switch (left) 3 and a marking switch (right) 4 are connected to the input side of 0. An electromagnetic valve (left) 9 and an electromagnetic valve (right) 10 are connected to the output side of the marking control device 20. Further, a predetermined output of the marking control device 20 is input to the control device 1.

Next, the internal structure of the marking control device 20 will be mainly described. In FIG. 6, the marking control device 20 includes a latch circuit 201, an AND circuit 202, and a timer circuit 2 corresponding to the marking switch 3 and the solenoid valve 9.
03, and the output of the marking switch 3 is input to the latch circuit 201. The output of the latch circuit 201 is input to the AND circuit 202, and a predetermined output Sm (marking permission command) from the control device 1 is also input to the AND circuit 2.
Has been entered in 02. The output of the AND circuit 202 is given to the solenoid valve 9 and also to the timer circuit 203. The timed output of the timer circuit 203 is given to the latch circuit 201 as a latch release signal. Latch circuit 20
The output of 1 is ON of the marking switch 3 (ON history).
It is given to the control device 1 as a signal indicating off.

Similarly, a latch circuit 204, an AND circuit 205, and a timer circuit 206 are provided corresponding to the marking switch 4 and the solenoid valve 10, and the marking switch 4
Is output to the latch circuit 204. Latch circuit 2
The output of 04 is input to the AND circuit 205, and the marking permission command Sm from the control device 1 is also sent to the AND circuit 20.
It is entered in 5. The output of the AND circuit 205 is given to the solenoid valve 10 and also to the timer circuit 206. The timed output of the timer circuit 206 is given to the latch circuit 204 as a latch release signal. Latch circuit 20
4 output is ON of marking switch 4 (ON history).
It is given to the control device 1 as a signal indicating off.

Next, the operation of the marking control device 20 configured as described above will be described. When the marking switch 3 is turned on, the on signal is latched by the latch circuit 201. The latched ON signal (H level) is given to the control device 1 and inputted to the AND circuit 202. At this time, if the marking permission command Sm (H level signal. The output timing will be described later.) Is not output from the control device 1, the other input of the AND circuit 202 is L level, and accordingly, the AND circuit 202 has the L level. The output is at L level. As a result, the solenoid valve 9 is not excited. In this state, the control device 1
When the marking permission command Sm is output from, the two inputs of the AND circuit 202 both become H level, and the output of the AND circuit 202 changes to H level. As a result, the solenoid valve 9 is excited, and the colored liquid ejector 1 corresponding to the solenoid valve 9 is excited.
3 jets the colored liquid. The timer circuit 203 is started when the excitation of the solenoid valve 9 is started, and after a predetermined time (for example, 5 seconds) has elapsed, the latch of the latch circuit 201 is released. As a result, the output of the latch circuit 201 becomes L level, the output of the AND circuit 202 also becomes L level, the solenoid valve 9 is de-energized, and the colored liquid injection is terminated. In addition, the latch circuit 20
The L level output signal of 1 is also given to the control device 1. As a result, the marking permission command Sm given to the AND circuit 202 from the control device 1 is also released.

When the marking switch 4 is turned on, the latch circuit 204, the AND circuit 205 and the timer circuit 206 operate in the same manner to control the solenoid valve 10.
When the marking switches 3 and 4 are both turned on, the corresponding circuits operate independently and the solenoid valve 9
And 10 are controlled. When the marking switches 3 and 4 are both turned on at the time when the marking permission command Sm is not yet output, the ON signal is latched when the marking switches 3 and 4 are turned on, and then the marking permission command Sm is output. Both solenoid valves 9 and 10 are energized all at once. On the other hand, when both the marking switches 3 and 4 are turned on after the marking permission command Sm is output, if the turning-on timings of both switches 3 and 4 are deviated, the turning-on signal of each turning on is turned on. It is latched and the corresponding solenoid valve 9 or 1
0 starts excitation at different timing. At the same time when the excitation is started, the respective timer circuits 203 and 206 are started,
When the set predetermined time elapses, the colored liquid ejection ends at different timings.

Next, the overall operation of the improperly processed marking apparatus according to the second embodiment will be described with reference to the flowchart of FIG. The flowchart of FIG. 7 differs from the flowchart of the first embodiment shown in FIG. 4 in that step 116 of FIG. 7 is provided instead of steps 107 and 108 of FIG. The operation in the other steps is the same as that in the first embodiment, and thus the description thereof is omitted. However, the detection judgment of the ON state of the marking switch in steps 104 and 113 of FIG. 7 is not the raw signal of the marking switches 3 and 4, but the latch circuit 201 of FIG.
And 204 output. Further, this detection judgment may be performed by determining whether or not at least one marking switch 3 or 4 is turned on, and it is not necessary to check whether or not both are turned on, as in the first embodiment. Absent. This is because the marking controller 20 directly controls the solenoid valves 9 and 10.
This is because the control device 1 does not need to identify and recognize the solenoid valve to be driven, and simply determines whether or not to perform marking.

That is, in the first embodiment, the control circuit 1 controls the function of judging whether a predetermined time has elapsed from the start of marking and stopping the marking (steps 107 and 108 in FIG. 4). However, in the present embodiment, the marking control device 20 controls these functions.
Therefore, with respect to marking, the control device 1 only gives a marking permission command Sm to the marking control device 20 (step 106) and receives a signal from the marking control device 20 informing that the marking is completed (step 116). To do. Specifically, when the X-ray inspection apparatus 2 detects an unsuitable crushing process (Y in step 102), at least one of the marking switches 3 and 4 is turned on before the conveyance distance of the conveyor 7 reaches a predetermined distance. If the marking control device 20 is operated, the marking control device 20 is operated at the time when the transport distance of the conveyor 7 reaches a predetermined distance.
A marking permission command Sm is output to (steps 104 to 106). Further, if none of the marking switches 3 and 4 and the pass switch 5 is turned on by the time the convey distance of the conveyer 7 reaches a predetermined distance, the conveyer 7 is stopped (steps 104, 110, 111).
And 112), when the marking switch 3 or 4 is turned on after the stop, the marking permission command Sm is output to the marking control device 20 at that time (Y from step 113 to step 106).

In the marking control device 20, when the marking permission command Sm is given from the control device 1, if the marking switch 3 is turned on, the output of the AND circuit 202 becomes H level and the solenoid valve 9 is turned on. The colored liquid is jetted by being excited. The excitation of the solenoid valve 9 and the injection of the colored liquid are ended when the timer 203 releases the latch of the latch circuit 201 for a limited time. Latch circuit 201
The L-level output is given to the control device 1 as a marking end signal. Similarly, when the marking switch 4 is turned on, the output of the AND circuit 205 becomes H level, the electromagnetic valve 10 is excited, and the colored liquid is ejected. The excitation of the solenoid valve 10 and the injection of the colored liquid are ended when the timer 206 releases the latch of the latch circuit 204 for the time limit. The L level output of the latch circuit 204 is given to the control device 1 as a marking end signal.
If both marking switches 3 and 4 are turned on, both of the above operations are performed. Control circuit 1
When the signals received from the latch circuits 201 and 204 are both at the L level, it can be determined that the marking is completed (Y in step 116).

In this way, the control load on the control device 1 can be reduced by causing the marking control device 20 to directly control the marking. Further, even when the marking switches 3 and 4 are turned on one after another, the signals can be reliably held by the latch circuits 201 and 204, so that the marking command of the one turned on later can be surely detected. Can be held.

In each of the above embodiments, the CPU
Although the configuration using the control device 1 including the above is shown, it is also possible to obtain a configuration in which an equivalent operation is performed only by hardware (a logic circuit, a relay sequence circuit, etc.) without using a CPU.

Further, in each of the above-described embodiments, the specific example of the "treatment" for the unsuitable material is limited to the "crushing treatment", but the marking device of the present invention uses other treatments (eg compression, incineration, etc.). It goes without saying that it can also be applied to inappropriate materials.

[0036]

The present invention constructed as described above has the following effects. The marking device for inappropriate treatment of the present invention,
Provided with a distance detection means for detecting the convey distance of the conveyor from when the processing inappropriate object is detected by the processing inappropriate object detecting means, when the processing inappropriate object is detected by the processing inappropriate object detecting means, the convey distance of the conveyor is When the predetermined distance is reached, the marking means is driven according to the marking instruction, and the control means is provided to stop the conveyor if no operation instruction is given by that time, so that a processing inappropriate object is detected. In this case, even if the marking command is issued early, it is possible to surely perform marking at proper timing, and it is possible to surely prevent passing of an unsuitable material without marking. .

Further, in the case where the operation command is not given by the above-mentioned time point and the marking means is driven according to the marking command received after the conveyor is stopped, the marking command is not output and the conveyor is not output. If is stopped, marking is performed by the subsequent marking command. Therefore, even if the marking command is delayed or forgotten, the marking can be surely performed.

Further, a marking switch for outputting a marking command and a path switch for outputting a marking stop command are provided, and when the control means receives the marking stop command, the conveyor is driven without marking. In such a case, by issuing a marking stop command from the pass switch, it is possible to convey an object that has been erroneously detected as an inappropriate processing object to the processing step.

Further, in the case where the inappropriate processing object is detected by the inappropriate processing object detecting means, if the marking command is given before the conveying distance of the conveyor reaches the predetermined distance,
The marking permission command is output at the time when the predetermined distance is reached, the conveyor is stopped if no operation command is given by that time, and if the marking command is given after the stop, that time is given. In the above, a main control means for outputting a marking permission command and a marking control means for latching and holding the marking command, performing marking according to the marking command and the marking permission command, and releasing the latched marking command in a timed manner are provided. In this case, the control load on the main control means can be reduced by causing the marking control means to perform the control related to marking. For example, even when a plurality of marking commands for marking on the left side and the right side of the conveyor in the conveying direction are issued one after another, the marking control means can reliably process the signal, so that the one issued later can be used. A marking command can also be reliably detected.
